invention relates to electrical protective systems and it particularly relates to centrally supervised Watchmens signal and lire alarm systems. l It is an object of the present invention to provide a system and arrangement for permanently and automatically recording tours of duty by Watchrnen, both in respect to time and location, in which the signals transmitted from the various lo Watchrnens boxes, particularly in the case of fire alarm signals, may be grouped separately from each other, so that confused recordings will not result from the simultaneous registering of signals from a plurality of boxes, the record made being in permanent form as required Without the need for recopying or transcription.

Another object is to provide a signal system for watchmen which will provide means for sending signals from signal stations to form autoga iiatically a complete visible record of their movements along their tours of duty and their approximate location at any time, and which will automatically operate to give a warning at the central station, directly to the supervisor in charge Without delay, if a Watchman is not performing or continuing upon his tour of duty in regular course.

Another object is to provide a central control station for Watchmens signal and re alarm systems which will automatically record the Watchniens movements, or their lack of movements, both by the flashing oi' lights and by duplicate permanent records, and will also provide for telephonie communication between the Watchman and the central station.

Another object is to provide a system of the character described which although it is provided with an automatic recording arrangement will give immediate indication upon the Watch- 4@ mans operation of a signal system Without the need for Waiting for the completion of or until an interval after the recording process.

Other objects are in part obvious and in part pointed out hereinafter.

The invention is primarily concerned with a protective signal system of the type in which a plurality of signal boxes or Watchmens stations are connected in an electrical circuit with a central supervisory and recording station, each o being provided with suitable circuit making and reaking arrangements to produc-e the desirable record at the central station.

In one form of the present invention the Watchmans actuation of the signal arrangements at a signal box or watchmans station Will be auto- (Cl. E34-37.5)

matically recorded both upon a tape register or recorder and upon a dial register or recorder. The tape and dial registers are preferably respectively actuated from separate circuits, passing through each of the signal stations or boxes. Gov The dial register is preferably directly actuated by a plurality of open circuits passing in parallel through the signal stations while the tape register is preferably actuated indirectly by a closed circuit through a subsidiary open circuit, said closed circuit passing in series through each of the boxes.

The dial register recording sheet is so laid out with said radial lines indicating the time, and concentric circles indicating the box that a per- 7o forated recording upon it Will indicate the box Which has been operated and the time of such operation. Where the signal is repeated a number of times, as in the case of a fire alarm, the perforation will be of increased size.

The tape register may be associated with a time stamp arrangement which will be actuated to stamp the time on the tape at the next minute following the recording of a signal thereupon. The time stamp is most desirably arranged so that it will not operate unless during the preceding minute a signal has been received and the tape has moved. Both the dial register and the tape register may be associated with lights which will flash upon the reception of signals, the dial register having an individual light for each box and the tape register having a single arrangement which Will be illuminated upon the reception of a signal from any box.

In one embodiment of the invention every box 96 is also provided with a telephone by means of which the central station or supervisor may be immediately reached through a loud speaker, an ear phone, and/or a bell, and a full oral report made as to the tour of duty of the Watchman or as to any untoward circumstances occurring during such tour of duty.

The system may also be provided with an automatic delinquency recorder which will indicate failure of a Watchman-to continue or complete 100 his tour of duty, or to appear at a station Within a predetermined period of time. Such failure Will be visibly recorded so that the supervisor Will be advised and may take appropriate action. The delinquency recorder is so arranged that normal operation of the signal system will prevent any record of delinquencies.

The tape register and lights associated therewith also serve to indicate any breaks and/or grounds in the system requiring attention and the system is further provided with suitable switching arrangements by means of Which it may be operated in spite of such breaks and/or grounds. These same devices will also indicate when the breaks or grounds have been repaired and will enable the supervisor to restore the circuits to normal condition Without delay.

Eigs..5, 6 and '7V show. the details. of the delinquency register, Fig.,l 5 being a fragmentary front view ofthe delinquency register, and Figs. @and 7 beingrespectively-top and side sectional views upon the lines 6-'-6 and 7-7-of Fig. 6.

InFig'. l'the conduits and instruments shown on the right of the dotted lline 1G extend 4and are positioned throughout the building or area to' be protected, while the various instruments and wiring on the left of the dotted line are in the central control station, or in the oce of the building where they are under observation and control' of a supervisor.

` Three signalstations or boxes 11, 12, 13are` illustratively shown, but it-is to be understood thaty any number of said boxes may be positioned ati various stations along the'tour of duty of the watchman throughoutfthe area to be patrolled and guarded. Each ofthese boxes is provided with a plurality of'ccntact's 14,15and 16 (see also Fig. 2), t'wo of which 15 and 1'6, rare normally openand oneY of which 14, is normally closed to form a continuous circuit throughV the conductors 17, 18, 1'9 and 20 through the boxes 1'1, 12,` 13 iii-series.A One side of each of the normally openl contacts l5 and 16 is grounded as indicated at 21. A- telephone arrangement 22 ma-yalso be provided in each box. Eachof the contacts 14, 15- and 16 (see yalso Fig. 2), are respectivelyv provided' with spring fingers. 29, BOand 31 having contact points 32, 33 and34 normallytogether in the case of contact 14 and normally separatedY in the case of contactsland 16'. The toothedsignal wheels 24, 26-and 27 are all mounted rigidly upon a manuallyl operable control member in the form of: a shaft'. 23' so that said wheels will turn together and upon rotation will cause successive closings of the contacts 15 and 16 and successive openings" of; the contact`14. f Preferably each box is altogether enclosed and may: only.: bei opened by the watchmans key. Upon; opening the b'oxthe watchmanby further operation of hiskey may actuate the box mechanism (notshovvn) to cause a single complete rotary ofitlie shaft` 23, and-of the toothed signal wheels 24; 26 and 27 thereupon. The signal WheelsA 24and '27 are each` provided with the same number and arrangement of teeth 25` and 28. (a single tooth followed' by vra group of three, an arrangement which varies from box to box). The teeth25 andi 28 are slightly displaced .angularly fromeachother sorthat. there will be an interval betweenv the opening` of the contact 14 and the closing of the contact 15. Upon operation of the box a code signal (in this particular instance) will be transmitted to the central supervisory station. The single tooth on the Wheel 26 will close the contact 16 momentarily and transmit a signal to the central station.

If desirable, at the same time the watchman may telephone to the station and inform the supervisor of his progressv upon his tour ci duty, or of any incidents which should be promptly reported. The boxes are also preferably provided "with another arrangement operated by a lever rather than by a key for causing a plurality of complete rotations of the wheels 24, 26 and 27, andisending in a plurality of signals which will serve asa. re alarm, the arrangement usually beingsuch as to cause repetition of the signals three or more times. Although the boxes are constructedto be opened by the watehrnans key before any signal may be transmitted to the central station, it is also desirable to provide a glass therein whichmay be broken by someone withm out a watchmans key to give access to a latch device which will permit opening of the box and actuation of the nre alarm lever. Upon actuation of any one of the boxes 11, 12 or 13 duplicate records will be made, the closing of contact 16 actuating the dial register or recorder 35and causing a flashing of the light 37 associated therewith, 'while the successive. openings and clo-` sures of the contacts14 and 15Will causeoperation of the tape register or recorder 39, the time stamp or yrecording device 40 and the lights 38.

The. closing of the contact 16 of box 11 will complete a circuit through the ground 2l', the conductor in parallel through the V:solenoid 5l andthe lamp 37', the balancing resistance 52, the conductor 53-to the operating battery 54 and the ground 55. The closing of the contacts .162 and 163 in boxes l2 and 13 will similarly complete circuits from the grounds 212 and 213 to the ground 55, similarly functioning individual conductors, solenoids and lamps being indicated by the same numerals as in the cas-eef the .circuit closed by the contact 16f distinguished, however, by a superior 2 or 3.

The dial register 36 (as also Figs. 3 and 4) is provided with a recording dial 42 which is rotated by aclock arrangement (not shown) below elongated finger 43. The finger 43 is provided With a plurality of screws 44, each carrying a projecting point 45. Beneath the dialV are the solenoids 51 (only one of which is illustratively shown in Fig. 4), each of which is provided with an armature 46. The armatures 45 carry perforating or pin devices 47 which are adapted to be moved upwardly when the solenoid is energized and to cause a mark orreadily visible perforation on the dial 42 immediately between the points 45. The dial is ruled with a series of concentric circles thereupon, one for each box or signal station and also provided with radial lines 49 which are so arranged and moved that the time designated thereuponv will correspond with the time at which the perforatoncr visible indication is made upon the dial42. The corresponding lights 37', 372 and 373, which vmay be conveniently positioned alongside the dial register will hash upon rsending in of the Will serve as an immediate signal, even before the permanent recordation is made, or while it uri the signal boxes by the contacts 14', 142 and 143 and conductors 17, 18, 19 and 20 also includes the ground 55, the battery 54, the conductor 71, the solenoid 72, the balancing resistance 78 and the milliammeter 74 on the battery side o1" the boxes, and the conductor 75, the balancing resistance 76, the solenoid 77, the conductor 78, the contact 80 or the tri-polar or transmitting switch 79 and the ground 81 on the other side of the boxes.

The solenoids 72 and 77 form parts of the relays which are provided with armatures 87 and 88 normally closing the upper contacts 89 and 90 of said relays respectively.

When one of the contacts 14', 142 and 143 is opened, upon operation of one of the signal stations or boxes, the solenoids 72 and 77 will be deu energized, the armatures 87 and 38 will drop and the alternate contacts and 96 or the relays will be closed. Upon closing oi contacts 95 and 96 the current will flow from the battery 91 through the conductor 92, then in parallel through the armatures 87 and 88, the contacts 95 and 96, the conductors 97 and 98, the contacts 802 and 803 and the conductors 99 and 100, the lamps 38 and 382. The circuit, which has already been split into two parallel paths, is further split into four parallel paths, two of which pass through the lamps 30 and 382 and reunite in the conductor 94.

The other two parts are through the conductors 101 and 102 through the solenoids 103 and 104 in the tape register device 39 where they may actuate printing devices on different sides of the tape. rhese paths then unite in the conductor 105 to pass through the solenoid 106 and through the conductor 93 back to the battery 91.

The contacts 14 and 15 actuate two circuits. The action of the teeth 25 of the wheel 24 upon the contact 14 causes the circuit between the ground 55 and the ground 21 to be opened, while the action of the teeth 28 of the wheel 27 upon the contact 15 causes the circuit from the ground 55, through the solenoid 72 and to the ground 21 to be closed. The tooth 29 oi the wheel 20 acts upon the contact 16 to close the circuit from the ground 55 through the lamps 37 and the recording device oi Fig. 3 to the ground 21. When one of the contacts 14 is opened, assuming that the corresponding contact 15 is left opened, the circuit between the ground 55 and the ground 81 is opened, and the solenoids 72 and 77 deenergised, thereby causing the lamps 38 and 382 to be lit, and the tape recorder 39 to be operated. 1i the contact 1'5 is closed simultaneously with the opening of the contact 14 the circuit between 55 and 21 would be closed, the solenoid 77 alone being deenergized. It is seen, therefore, that if the contacts 14 and 15 should be operated simultaneously, the circuit from the ground 55 through the solenoid 72 to the ground 2l would always be closed, so that this circuit would be rendered useless as far as its action on one of the signal lamps 88 is concerned. 1n order to avoid this condition, the sets of teeth 25 and 28 oi the wheels 24 and 27 respectively are placed at slight angular displacements to one another, so that the contacts 14 and 15 are not operated simultaneously. With the teeth of one wheel angularly displaced with respect to the teeth or" the other wheel as shown, the operation of both circuits upon the signal lamps 38 and 882 will be assured.

Energization of the solenoid 106 will elevate the armatures 152 and 153, the armature 158 closing a subsidiary circuit including the resistance 160, the silver contact 154 and the conductors 161 and 162. This will continue energization of the solenoid 106 and lock the armatures 153 and 152 in position even after the initial circuit through the tape register 39 has been opened by reenergization of the solenoids 72 and 77.

The time stamp device 40 is controlled through the master clocl; 121 and the double relay 122 which are supplied from volt source 123, preierably of the DC type. The relay is adapted to connect the source 125` to the winding circuit 124 and 125 of the master clock 121 by closing the gap between contacts 126and 127, and 128 and 129 respectively.

1t is also adapted to close the minute impulse circuit to the time stamp 40 through the conductors 141, 142, 14B and 144 by closing the gaps between the contacts and 146, and 147 and 148 respectively. The minute impulse circuit cominunicates an impulse every minute to the time stamp 40 and sets the clock device therein to agree with the master clock 121.

ince it is only desirable to have the device 40 mark the tape of the register 39 after the recording of signals thereupon an arrangement is provided whereby the time stamp will not be actuated unless its circuit has been previously closed by the energization of the solenoid 106 incidental to transmission oi a signal from a box. The actuating circuit 149 and 150 from the relay 122 to the time stamp 40 is provided with At the same time the solenoid will be energized to raise the armature 156 and close the contact 157. This will establish a shunt circuit around the solenoid 106 as a result of which it will be deenergized, the armatures 152 and 153 will drop and the contacts 151 and 154 will be opened.

The operation of the system is as follows: The signal boxes 1l, 12 and 13 are positioned at suitably design-ated positions about the plant or area to be protected and guarded and the i1 watchman is instructed to operate these boxes in certain order and at certain time intervals. As the watchman actuates any box, the closing of the contact 16 by rotation of the wheel 26 will cause an instantaneous illumination of the corresponding lamp 37 and energization of the corresponding solenoid 51 oi the dial register 36 with perforation of the dial indicating the box operated and the time of such operation. The perforation will be made between the points 45, upon the circle assigned to the signal box operated and upon a radial line corresponding to the time of perforation and may be irnmediately observed. At the same time, the wheels 24 and 27 will be rotated to alternately open close the contacts 14 and 15. A series of dashes will be formed upon the tape of register 89 corresponding to the code number of the box and both lamps 38 will burn to give a series oi flashes also corresponding to said code signal.

Upon operation of the tape register 39 and illumination of the lamps 38, the solenoid 106 will be energized and will lift the armatures 152 153 to close the contacts 151 and 154, the closing of the latter Contact locking the a1'- matures in position and the former closing the time stamp actuating circuit.

The next operating impulse from the master clock121, which impulses will ordinarily occur every minute, will then pass through the contact 151 to actuate the time stamp 40. At the same time this impulse will energize solenoid 155, which will lift the armature 156 and close the contact 157. The shunt circuit thus established around solenoid 106 will ,result in its deenergization. As a result the armatures 152 and 153 will fall, opening the contact 151 in the time stamp actuating circuit.

Another operating impulse will not be communicated to the stamp 40 until the solenoid 106 has again been energized by a signal and the contact 151 closed.

If desired, a conventional telephone arrangement 22 may be placed in every box and connected by the conductors 165 and 166 with a telephone mouthpiece 167 and earpiece 168 in the supervisors office, the battery 169 supplying the necessary current. The ear phone 168 may be replaced or combined with a loud speaker and/,or a bell arrangement so that the 'watchman` may signal to the central oice for telephonie reports, either at every box, at certain boxes and/or in case of emergency and any untoward occurrences.

If desired, the system may also be combined with the annunciator arrangement'by means of which the watchman could be called to the nearest box for the purpose of communicating directly with the supervisor by means of the telephone.

Upon the line 53 may be positioned the delinquency register 190 which is connected to the solenoid 192 in the dial register 36 by the conductor 191. The delinquency register (see Figs. 5, 6 and 7) is provided with a standard clock driving gear train 193, 194, 195v and 196 which turn a cam-shaped dial 197 corresponding to an hour hand making one revolution in 24 hours. The dial may be set in any desired position by the setting device 198. The dial 197 is provided with a follower 199 which is adapted to ride over the depressed portion 200, during the night time when the watohmen are on duty, and over the elevated portion 201 during the day time when the signal system in not in operation.

The clock mechanism gear train 193, 194, 195 and 196 isl also adapted to drive a large gear wheel 205 which in turn drives the pinion 206 and through said pinion the worm 207. The follower 199 is provided with an arm 202 having a pin 203 contacting with the bar 204. The contact bar 204 is provided with a depending follower stud 208 which cooperates with the worm 207. As a result of the coaction of the pin 203 andthe bar 204, the stud 208 is lowered into operative position when the follower is traversing the depressed portion200 of the dial 197 and is elevated into inoperative position when the follower is traversing the elevated portion 201 of said dial 197.

The contact bar 204 is provided with two spring ngers 209 and 210 (see particularly Fig. 6), which have contact points 211 and 212, one of said fingers being connected through the conductors 191 and53 and the solenoid 225 to the battery 54 and the other being connected to a ground by suitable connections to the binding posts 56 and 57 respectively. The contact bar 204 will be moved rearwardly of the device by interaction of the stud 208 withthe worm 207.

` The contacts 211 and212will remain separated until the spring ngers 209 and 210 have been pressed together by contact with the-pin 213 (see also Fig. 7). The pin 213 is provided with a head for manual manipulation and may be placed in any one of the resilient split depending cylindrical receivers 215 attached to the ilange 216, which flange is supported from the clock structure. The position of the pm 213 determines the amount of movement of the contact bar 204 before closing of the contacts 211 and 212.

l Since it is only desirable to have the contacts 211 and 212 close and energize the solenoid 192 when the watchman has failed to continue his tour of duty or when too great a lapse of time has occurred from the time of the last signal, an arrangement is provided to return the contact bar 204 and the follower stud 208 to initial position every time a signal is transmitted from the watchmans signal box to the central supervisory control station. For this purpose a solenoid 225 is placed in the normally open circuit by connecting the conductor 53 to the binding posts 58 and 59. With the solenoid 225 is associated the armature 226 which has a rearwardly projecting finger 227 rovided with a vertical depending ange 228. Contact between the lower edge of the fiange 228 and the lever arm 229 of the pivot bar 204 is maintained by the leaf spring 233, the inner portion of which is wrapped around the pivot post 230.

When the stud 203 is disengaged from the worm 207, the lever arm 229 is drawn rearwardly by the spring 231 This movement is limited by a downwardly projecting finger 234 from the ange 228.

The Contact bar 204 is pivoted at stud 230 by the screw 232, the head of which is spaced to permit either lateral horizontal pivotal movements or vertical seesaw movements.

When the circuit through the conductor 53 is closed upon transmission of a signal the current will flow through the solenoid 225, elevate the armature 226 and cause the ange 228 to depress the lever arm 229. This will elevate the follower stud 208 out of the worm 207, and the spring 231 will thereupon move the lever arm 229 of the contact bar 204 against the stop 234 and the stud 203 outwardly. Upon opening of the circuit 53 again, said stud will be lowered into the rst turn of the Worm 207.

The elevator device 235, which is provided with the stop 236, to contact with the post 230 when the device is not in operative position, may be used to permanently disengage the follower stud 203 from the worm 207. By turning the device counter-clockwise, its end portion 37 will contact with the bottom of the bar 204 and elevate it to disengage the stud 203.

Closing of the contacts 211 and 212 upon failure of any signal to come in after a length of time predetermined by the setting of the pin 213, will cause energization of the solenoid 192 (see Fig. 1) which is combined with a perforating arrangement of the same construction as shown in Fig. 4. The perforating needle in this instance, however, serves to form a perforation in a circle not assigned to the signal from any box.

In case the circuit 17, 13, 19 and 20 is grounded or breiten at any point. indication will be had by lighting of the lamps 38 and/or 382 and a continuous running of the tape register 39. The system may be immediately pnt into operative condition by throwing over the transmitting switch 79 and/ or the single switches 250 and 251.

For example in the case of a break, both the lamps 38 and 382 will burn, the line may be restored to operating condition by moving the switches 79 from the normal circuit contacts 8D to the open circuit contacts 252. This movement of the switch 79 will extinguish the lights e8, will stop operation or^ the tape register 39, will eliminate the ground 81 and will connect the positive side of the battery 5e to both sides of the circuit. As a result, twoopen circuits will be formed, one including the contact 2522, and 'the conductors 78, and 20, and the other includ-- ing the conductors 58 and 50. Upon actuation of a box the circuit will be completed from 'tho ground 55 to the ground 21 or the box so actuated. When the sii/'itch 79 is placed in this position, the solenoids 72 and 77 will have been deenergized and the armatures 08 and 87 will have fallen from the contacts 90 and 89. Whereupon the circuit through the lamps 88 and the tape register 39 will be normally open and completed upon energization of either the solenoid 72 or 77. Completion of the circuit will light one of the lamps 38 and act-nate one of the solenoids 108 or 18e of the tape register 39. When the break is repaired the transmitting switch 79 may be thrown from its open 252 position to its normal 80 position, whereupon the line will again be in its normal operative position.

The testing arrangement 180 is provided with a voltmeter 181 and with a series of plug-in arrangements 182, 183, 184, 185 and 186. These plug-in arrangements are adapted to cooperate with a manually inserted plug to close a circuit across the voltmeter and give a voltage reading thereupon. The plug-in arrangement 182 will indicate the voltage between the line 17 and the line 20; the arrangement 183 the voltage between the line 2O and the ground 187; the arrangement 184 the voltage between the ground 187 and the conductor 17; and the plug-in arrangements 185 and 186 respectively the voltages of the local battery 91 and the telephone battery 1.69.

It is most convenient for purposes of central control to place the testing arrangement 180,`the voltmeter 181, the milliammeter 7d, the normal and ground solenoid-armature arrangements Y2-88 and 77-87, the transmitting switch 79, the single switches 251 and 250, the lamps 88 and the Vrelay arrangements 106-152-158 and 155-158 upon a single central control board.

The signaling and recording installations and the delinquency register of the present invention, may be widely applied to other systems, than the lwatchmans and re alarm systems specically described. For example they may be applied to sprinkler and low water alarm systems and to many other electrical control arrangements.
